The good thing about Pokerstars is that you can find other formats, such as 8 Game, which I especially like. You can also find 2-7 Triple Draw and 2-7 Single Draw and traditional 5 Card Draw, so you can choose from.
I like razz, but it’s better in mixed versions than 8 Game and Stud H / L, so the game is more complex and the knowledge can come out better.
Good luck.
